Too Wylde To Tame by Chasity Bowlin

The third book in The Wylde Wallflowers Series…

Charity Wylde has always been… well… wild. The devil to her staid twin sister’s angel, their parents had despaired of her ever making a suitable match. In truth, so had she. Too loud. Too raucous. Too quick to draw attention to herself. And that is precisely what gets Charity into trouble.
Attending a ball with her aunt, she draws the eye of a notorious gentleman. A seducer, a rogue, a ne’er do well—Lord Jameson Dartwell is avoided by almost every woman in society except those naive enough not to know better. And sweet, trusting, high spirited Charity fits that category nicely.
There’s only one problem. His well behaved older brother, Lord Fredrick Dartwell, Viscount Wellbeigh, saw her first. He doesn’t wish to seduce Charity, but to possess her. To make her his, body and soul. If that means he has to play his brother’s game and seduce her first, that’s the kind of sacrifice he’s both willing and eager to make. But unlike his brother, he has no intention of discarding her when he’s done.

Once Charity is his, she’ll be his forever… and he will be hers.
